T 0 all 1li/wm e' 17 may fof/mcra- 4Be it known 'thatL lVnqsroN H. Fianna,

a citizen of the United Statesyresidingat Si, Albans.v in theA conntyxof'Franklin and State o'l' vVernion'tylravo invented eertaiiinewand usefullniprm'enieuts in va `lnivatory Stopper, of whichthelollownigiis a specilication.`

This invention relates to'improvements in" Stoppers for use particularly in connection with thewaste-.outlet Ior drainbf a `lavatory, and has forv its principal object #tor provide a means for preventing an overflow.4

@ne ot the important; objects of the pres` ent iiiventionis to provide `a stopper oli the above mentioned character,` wherein meansY is associated therewith for automatically allowing the warte 1- inthe 1washbasinyto `be discliargedV outwardly into the waste-outlet upon the water reaching -a zpredetermined-` level in the basin.

A still further object f. is to provide ai stopper of the above mentioned character,

which includes an vauxiliary stopper, saidk V,stopper of the above mentioned character,V which is simple in construction, inexpensive,

strong and durable and further well adaptn ed for the purposes designed. v

@ther ob'ects and advantages of this in vention will become apparent during the course of the following description.

ln the accompanying drawing, forming a part lof this specification, and in which like numerals designate like parts throughout the same:

The ligure represents a view partly in section, and partly in elevation of the stop per embodying my invention.

In the drawing, wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates a stopper which is of a conventional construction, the same being adapted to be removably inserted in the usual waste the top-ofthe stopperfare passages 3 The purpose thereof wn-ll,l ybe herelnattor` on the central portion of the plate 5.

'outletVV or i drain' provided in the i bottom of a wash basin. A` centrally located opening 2 is formed in the-bottom of the stopper and diverging upwardly therefrom` through more fully described.

Forming a closure for the f central open-r ing is. theplate or disco, the same being adapted for engagen'ient with ythe bottomzof the stopper' 1 in the manner as clearly il lustrated inthe drawing. Extending eenl trally in tlieupper portion-of tliestopper:V

1 is the bolt 6, the-head 'Z vthereof 'adapter to support thenring 8, the purpose-of'which 1s to provide-ia means for-insert1ng-andrev o moving-.the stopper' for thepurposeiwell known 1n the art. The threaded end 9 of? the bolt extendsdownwardlyyinto Athe interi' inediate'portion of the stopper at the point of intersection of tliefupwardly converging passages A3 and fl. A nut 10 is threzu'led-oni` the lower threaded end'of the bolt and is operable within asuitablecut outuportionall providedotlierefor in vtlieyuppe'r portion ofsthestoppera. y i L An upwardly extending lug 12 is formed A coil spring 13 is secured at its lower end to said lug, and at its upper end to said nut 10. The purpose of the coil spring 13 is to normally hold the plate 5 in engagement with the bottom of the stopper 1 whereby the opening 2 is normally closed. The tension of the coil springl is regulated by rotating the bolt 6 through the medium of the ring 8 causing the nut 10 to bemoved along the threaded portion `i) lof the bolt in the manner as is obvious from the construction..illustrated.

When the stopper 1 is' in the usual waste outlet provided in the bottom of a Wash basin, the latter is filled with water in the usual manner. Upon the water reaching a predetermined lie-ight or level in the basin, the weight of the water will exert a downward pressure on the plate 5 causing the same to move downwardly away from the bottom of the stopper and uncevering the opening 2. This permits any excess water to flow through the passages 3 and l, and through the opening 2 into the waste outlet pipe so that the wash basin will not overflow. After 'the surplus water has been discharged froni the wash basin, the coil spring 13 will return the plate 5 to its normal position closing the opening 2 and preventing the water in the basin from being emptied or discharged therefrom. The stopper 1 is adapted to be removed from the waste outlet in the usual manner in orde-r to discharge the water from the lavatory.

The simplicity in which my improved stopper is constructed, enables the tension of the spring to be regulated in such a` manner as to control the actuation of the plate so that the latter may be caused to operate at any desired level reached by the water in the lavatory.; n Furthermore, a ystopper of the above mentioned character, will at all times be positive andeiiicient in its operation as well as automatic and will prevent any possibility of an 4overflow which often results by the use of the ordinary Stoppers.-

ing, a closure plate for said'outlet open# ing, means for normally holding the closure plate against the bottom of the stopper for preventing the flow of water through the outlet opening, said closure plate adapted to be `moved into an inoperative position whereby the outlet opening is uncovered when the water inthe lavatory reaches a predetermined level to permit the flow of the excess water through said outlet.

2. In a stopper for a lavatory, the same being provided with an outlet opening, a valve for said out-let opening, means for normally holding the same in a; closed position, said valve adapted to be opened when the' water in the lavatory reaches a predetermined level to permit the flow of the eX- cess water outwardlyy through the' water outlet opening, said means comprising a coil spring secured at one end to said valve and at its opposite end to the usual ring securing means associated with the stopper.

3. In a stopper for a lavatory, the same being provided with an outlet opening, a valve for said outlet opening, means for normally holding the same in a closed position, said valve adapted to be opened when the water in the lavatory reaches a predetermined level to permit the flow of the excess water outwardly through the water outlet opening, said means comprising'- a coil spring secured at one end to said valve and at its opposite end to the usual ring securing means associated withy the stopper, and means for adjusting the tension of said coil spring.

In testimony whereof `I aiiix my signature.
